A small fix deployed today to address an error in how the SRS bar chart displays flashcard counts when it is "compacted" in portrait mode (typically viewing on a smartphone).

When viewing the SRS chart in portrait mode on a small display, the total number of displayed boxes has to be reduced. To avoid scrolling sideways, the due/undue totals for box 8,9,10, etc. are added up into the last displayed box labelled "7+".

There was a bug here that would cause an incorrect due/undue count to be displayed, along with "flattening" the rest of the chart since the last pile was artificially higher. This bug had no effect on flashcards or reviews, just the way the bar chart is displayed.

Thanks to KanjiKalvin for reporting issue 329 on Github!
